Koshitan no longer wants to be driven crazy by Nokotan and decides to spy on her to find her weakness. This leads her to the zoo, where she observes Nokotan at work.
Hang on. We don't know 
that it's a love letter yet.
Noch wissen wir nicht,
ob es wirklich ein Liebesbrief ist …
No, digo, aún no sabemos
si es una carta de amor…
On ne sait même
si c’est vraiment une lettre d’amour…
Espere aí, a gente nem sabe se
é mesmo uma carta de amor...
